In OpenBGPD before 8.1, incorrect handling of BGP update data (length of path attributes) set by a potentially distant remote actor may cause the system to incorrectly reset a session. This is fixed in OpenBSD 7.3 errata 006. • https://blog.benjojo.co.uk/post/bgp-path-attributes-grave-error-handling https://ftp.openbsd.org/pub/OpenBSD/patches/7.3/common/006_bgpd.patch.sig https://github.com/openbgpd-portable/openbgpd-portable/releases/tag/8.1 https://news.ycombinator.com/item?id=37305800 https://www.openbsd.org/errata73.html • CWE-754: Improper Check for Unusual or Exceptional Conditions •

OpenBSD 7.3 before errata 014 is missing an argument-count bounds check in console terminal emulation. This could cause incorrect memory access and a kernel crash after receiving crafted DCS or CSI terminal escape sequences. OpenBSD 7.3 antes de la errata 014 carece de una comprobación de límites de recuento de argumentos en la emulación de terminal de consola. Esto podría provocar un acceso incorrecto a la memoria y un bloqueo del kernel tras recibir secuencias de escape de terminal DCS o CSI falsificadas. • https://ftp.openbsd.org/pub/OpenBSD/patches/7.3/common/014_wscons.patch.sig https://github.com/openbsd/src/commit/9d3f688f46eba347e96ff0ae9506ef2061622e0c • CWE-862: Missing Authorization •
CVSS: 9.8EPSS: 8%CPEs: 5EXPL: 8CVE-2023-38408 – openssh: Remote code execution in ssh-agent PKCS#11 support
https://notcve.org/view.php?id=CVE-2023-38408
The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path, leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an incomplete fix for CVE-2016-10009. La característica PKCS#11 en ssh-agent en OpenSSH anterior a 9.3p2 tiene una ruta de búsqueda insuficientemente confiable, lo que lleva a la ejecución remota de código si un agente se reenvía a un sistema controlado por un atacante. (El código en /usr/lib no es necesariamente seguro para cargar en ssh-agent). • https://github.com/kali-mx/CVE-2023-38408 https://github.com/LucasPDiniz/CVE-2023-38408 https://github.com/classic130/CVE-2023-38408 https://github.com/mrtacojr/CVE-2023-38408 https://github.com/wxrdnx/CVE-2023-38408 http://packetstormsecurity.com/files/173661/OpenSSH-Forwarded-SSH-Agent-Remote-Code-Execution.html http://www.openwall.com/lists/oss-security/2023/07/20/1 http://www.openwall.com/lists/oss-security/2023/07/20/2 http://www.openwall.com/lists/oss-security/ • CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-428: Unquoted Search Path or Element •
